(CBS) Of all the positional groups on the Bears, the linebacking corps are most unsettled heading into training camp. Three players are battling for two open spots, and no one’s sure how it will play out.

Including a man in the mix, D.J. Williams, who didn’t initially understand the Bears’ vision for competition breeding success. Williams told CSNChicago.com that he didn’t receive full details of the linebacker competition when he signed a one-year contract in the spring that could be worth $1.5 million, apparently expressing surprise at Shea McClellin’s new role as a full-time linebacker.

That switch has helped create a battle at middle linebacker between Williams and second-year pro Jon Bostic, who is also battling for time at strong-side linebacker with McClellin. Lance Briggs will man the weak-side linebacker spot.

While admitting he “might have looked at other situations” more closely in free agency if he knew what he knows now, Williams is also handling the situation like a pro. It’s his job to be one of the three best, and that’s what he plans on doing.

“I’m coming here to fight it out, duke it out,” Williams said, according to CSNChicago.com.

“Personally, I feel like I’m one of the three best linebackers on this team, and if I’m healthy, stay focused, do everything I’m supposed to do, I should be in there.”

Williams missed the final 10 games of last year with a pectoral injury.
